Benefits of technology

The invention aims to make recording devices smaller by eliminating the need for a support member and reducing the size of transport rollers.

Problems solved by technology

However, the driving roller is connected to a power source and cannot freely rotate.
Thus, upon comparison with the driven roller, the driving roller does not operate in such a way that the driving roller causes the following edge of the medium to be forcefully pushed out.

Abstract

Provided is a printer which includes a carriage which includes a recording head performing recording on a paper sheet, a transport driving roller which transports the paper sheet to the recording head side and is driven by a driving source, and a transport driven roller which is pressed to the transport driving roller, is rotationally driven in contact with the paper sheet, and has a diameter larger than that of the transport driving roller. The transport driving roller is located below a guide frame as a support member supporting the carriage and is located in an area of the guide frame in a paper transport direction (in other words, a y direction).

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to a recording apparatus represented by a facsimile or a printer.[0003]2. Related Art[0004]In an ink jet printer as an example of a recording apparatus, a pair of transport rollers which transport a recording paper sheet as an example of a medium is provided on an upstream side of a recording head. Generally, the pair of transport rollers is constituted of a driving roller driven by a motor and a driven roller pressed to the driving roller.[0005]There is a so-called serial-type printer in which a carriage including a recording head can move in a scanning direction of the recording head. In such a serial-type printer, the carriage is supported by a support member (in other words, a guide member) and is guided in the scanning direction of the recording head. An example of such a serial-type recording apparatus is disclosed in JP-A-2006-247932.[0006]Examples of the support member supporting the carriage include a sha...
